Check Your Site Operations
"A computer lets
you make more mistakes faster than any invention in human history - with
the possible exceptions of handguns and tequila."
-Mitch Ratliffe
Online Tools to Test Web Site Performance:
Is your site fast
enough? The typical visitor is a dial-up user who will not wait more than
10 seconds for a page to load. Users who don't find what they want the
first visit, frequently never come back and a significant number will
go directly to a competitor. Your business may depend on your web site's
speed.
Speed is not the only
issue. Does site copy include spelling errors? Is the HTML properly constructed?
Are there any errors in coding that could cause problems?
W3C HTML Validation
Service

to W3C Recommendations and other standards. You can also check your Cascading
Style Sheets using W3C's CSS Validation Service.

speeds.

Webpage Size Checker
http://www.searchengineworld.com/cgi-bin/page_size.cgi
Is your
site too big to load quickly? If a page doesn't load in 8 seconds, you
could lose 1/3 of your visitors. Here's a tool from PHD Software Systems
that checks page size.
Check Your Cacheability
http://www.web-caching.com/cacheability.html
Does new site content really make it to your visitors? Some visitors could
have an older version of your site's pages stored in cache, on their hard
drive. Use this application to check your site's cacheability.
Screen Size Tester
http://www.dotfactor.com/tools/develop/htmlscreensizetester.shtml
This tool
from DotFactor.com allows you to check to see if your site can be viewed
correctly in at different screen resolutions. Many designers recommend
that at a minimum, web sites should work with at least 800 x 600 to 1024
x 768 screen resolutions, without the need for horizontal scrolling.

Can users
with disabilities access the web site information? Do text-to-speech applications
work? Can the site be navigated with only the keyboard? Bobby WorldWide
is a tool for Web page authors. It helps identify changes to pages so
users with disabilities can more easily use them.
